Early Days of Seismic Field Operations in Western Canada

Bob Rintoul

…As presented to the Petroleum History Society at their luncheon in Calgary on June 20, 2007. Reproduced from PHS website – see http://www.petroleumhistory.ca/history/speeches/rintoul.html First of all I would like to advise, this is not a scientific paper but one which gives us a first hand look at the trials and…

Near Surface Geophysics as an Aid to Horizontal Drilling for Pipeline Construction

Paul Bauman and Christeen Nahas

…Background In near surface environmental geophysics, the provider of such services will often propose that carrying out such work will save the client money in the overall project. Occasionally, and often in direct correlation with the quality of the work, such services result in increased budgets over the short term.…

A simple way to speed up wave equation migration: using a time-shift imaging condition

Mark Ng

…Abstract This article describes a way to speed up downward continuation wave equation migration (WEM) by 200% to 400%, or more, via modification of the conventional imaging condition. Specifically, I introduce a new ‘time-shift’ imaging condition, which can be used to estimate the migrated image in between actual migration depth…

A Geophysical Facies Description of Quaternary Channels in Northern Alberta

Richard Kellett

…Abstract Buried glacial channels in the surficial sediments of northern Alberta and British Columbia have been the focus of several industry and academic research groups in the last 5 years. Individual channels can be over 50 km long, two to five km wide, and have been incised up to 300…

…Remaining Silent “Better to remain silent and be thought a fool, than to speak and remove all doubt.” Attributed to Abraham Lincoln One of the most difficult lessons I have learned in life is when to remain silent. On more than a few occasions the mere fact that I know…

Executive Message

…It has been an honour and a pleasure to serve as Finance Director this year. We have had another very successful year, and our finances are in tip top shape. However, the challenge of this sort of position is to prudently estimate the future and save and budget accordingly. “May…

CAGC Column

…Stelmach finally did make up his mind on Royalties. For our industry the 5 weeks of indecision was the worst part. Once a decision was announced companies started to release programs and bids. As some of the seismic channel content has moved south to the US during the periods of…

Preparing for the Future in Geophysics: Out of the Darkness and into the “Lite”

Alan Cohen

…This speaker was invited to give the keynote address at the fall 2005 Doodle Train but was unable to attend due to complications from hurricane Katrina. The story is told of his flight from New Orleans, the loss of his house, his journey to Lafayette, and his subsequent efforts to…

CGGVeritas Marine Fleet Upgrade and Renewal

Richard Price

…Editors’ comment: One exciting aspect of marine seismic is the continual technical improvements the marine seismic contractors bring to market. The following is an update from CGGVeritas, and we hope to publish similar submissions from the other marine acquisition companies in future issues. The creation of the CGGVeritas marine acquisition…

Investing in EM

Richard Kellett

…Is it the right time to invest in electromagnetic techniques? This question is being asked from a wide range of perspectives: From an exploration geophysicist’s perspective will EM help reduce risk on a target that has some ambiguous seismic characteristics? For a chief geoscientist, the question might be; “Is it…

Improving AVO fidelity by NMO stretching and offset dependent tuning corrections

Yong Xu and Satinder Chopra

…Summary Wavelet stretching due to NMO correction of seismic gathers causes problems in AVO. Coupled with the degrading action of wavelet stretching is offset dependent tuning for thin beds. Even though tuning is inherent in the data before NMO correction, its effect on AVO is more obvious on NMO corrected…

Seismic curvature attributes for mapping faults/fractures, and other stratigraphic features

Satinder Chopra and Kurt Marfurt

…Seismic attributes are a powerful aid to seismic interpretation, providing geoscientists with alternative images of faults and channels that can be used as components in unraveling the depositional environment structural deformation history. While seismic attributes have been used for nearly four decades, some of the most significant attribute developments and…

Tako Koning

An Interview with Tako Koning

…Tako, let’s begin by asking you about your educational background and your work experience. I was born in Holland in 1949. In 1954 my family emigrated to Canada and I grew up in Edmonton. People sometimes wonder where my name came from and I tell them I am Holland-born but…
